11 Claims. (01.146-102) My invention relates to animprovement in slicingmachines, and has for one purpose the provision of an improved slice deflecting means.

Another purpose is the provision of slice support A.

ingtmeans effective at the pointfof severance of theslice. Another object is the provision of means for preventing the" access of fOreignEmaterial to the spacein front of or beneath the slice receiver; Another purpose is the provision-"of means for deflecting materialinto the "forward are preferably unitary. Other objects will a'ppear from time to time in the course of thespeci- 15* grammatically in fication and claims.

ness of the slice. j It is mounted upon any suitablesupport C which is provided with rods slidably mountedin the base A. Movement of these rods and therefore of the 'entire gauge plate assembly is obtained by movement of the manual control lever C The details of-this lever and of the driving connection between it and thegauge plate are not indicated, as they do not of themselves form part of the present invention. Itwill be understood that when the handlegC is 10 in the position in which it is shown in FigureZ the gaugeplate is advanced as nearly as it can be to-the cuttingplaneof the knife and may even be set to mask the edgeof the knife. When the handle C is moved to the opposite end of its possible excursion; the gaugeplate' and its assembly, are moved to; the leftgreferring-tothe parts in the position in which they are shown in Figure 5. The position of the gauge plate-when withdrawn is shown in dotted lines in Figures 2 and 6 It will be noted; for example from Figure 2, that the rods 0 are set at a slight angle so-that the path of the gaugeplate is inclined in relation to the cutting plane, the gaugeplate being drawn later- .ally somewhat awayfromthefcutting edge of the knife as it recedes. l

. A slice receiving trayD is removablypositioned upon the base A and above the actuating means for the gauge plate C. Itis provided with a forward flange D clearly shown for example in Figures Band Land alsoin Figure 5, and it is forwardly offset at D adjacent to the cutting edge of the knife, as shown for example in a dotted line in Figure 2. At that point it approaches very closely to the pan or refuse trough D which a is removably positionedon the side of the cutting plane opposed to the slice receiver D. The contour ofhorizontal plane of the pan will be clear fromFigure'2,:part of the pan extending rearwardly'of the cuttingplane of the knife as at D 40 In a slicing machine, which is currently used to slice foods such as meats and which may be in almost constant use, it is highly desirable that fragments and juices of the material being cut do'not penetrate into parts of the'machine where theyare likely to gather and decay. In my presentinventionfI provide effective means for re- ,ducingtoa minimum the tendency of particles,

' juices, grease and the like from penetrating into hidden corners of the machine. In the first place,

' I provide means for insuring that the slice and member being shown in plan view, for example in Figures 2 and 4.

It is mounted on the base by any suitable bolts or screws E It includes an extended body portion in the form of an inclined or downwardly and outwardly curved eave E mounted upon bosses E into which penetrate the screws E The curved eave'E underlies the gauge plate support at all positions of-the gauge plate, as will be clear for example from Figure 5. In other words, no matter where the gauge plate and its support may be the downwardly curved eave E bridges the gap between the gauge plate support or the lower edge of the gauge plate'C and the upstanding flange D of the slice receiver D. The eave E extends outwardly and rearwardly beyond the face of the gauge plate even when the gauge plate C is at its most rearwardly position. This will be clear from the position of the gauge plate C in dotted lines as illustrated in Figures 2 and 6. Associated with the member E at the right hand end referring to the parts in the position in which they are shown in Figures 2, 3 and4 is an upward projection generally indicated as E which is provided with a" small flat edge E flying generally in the plane of the carriage later to be described. Associated with it is an angular portion E extending rearwardly from the cutting plane and conforming generally'to the contour of the knife blade. The slices, as they are severed, slide down along the member E and are directed thereby away from the knife so that they fall upon the slice receiver D. It will be noted that the upright edge of the member E1 is inclined as at E D and the pan D The shape changes at different points along its length but this bridging function will be clear, for example, from'the sections Figure 7 and Figure 8. The'upper portion of this member E also conforms generally to the V arc of the knife as at E although the gap opens slightly as is clear from Figures 1 and 3, the two arcs being eccentric. Y p

G, G indicates a plurality of tracks upon which is slidably mounted any suitable work supporting carriage generally indicated as G It 'has also a work supporting surface G shown as forwardly inclined and terminating at its forward edge in a flange G G is a pusher plate, the de tails of which do not form a part of the present invention. 1

It will be realized that whereas I have. shown a practical and operative device, nevertheless many changes may be made in size, shape, number and disposition-ofparts without departing from the spirit of my invention. I, therefore, wish my description and drawings to be taken as in a broad sense illustrative or diagrammatic rather than was limiting me to the precise details disclosed.

The use and operation'of my invention. are as follows:

.. The operator puts apiece of foodsuch as meat on the supporting surface G of the carriage G He may press it forward against the gauge plate C by urging the pusher plate G The gauge plate C is set to gauge the desired slice thickness. The operator then urges the carriage G2 as a whole toward the cutting edge of the knife and the knife cuts a slice of the gauged thickness. The rest of the meat passes forwardly across the guard plate B Any grease which is deposited on the knife A is picked up by the scraper H which is shown as mounted upon the guard plate B The grease or material from this scraper drops into the refuse pan D which at that point extends beneath the scraper and well to the rear of the cutting plane of the knife as shown at D in Figure 2. The severed slices are deposited upon the slice receiver D. The work and slice is supported at the point of severance by the member E This tends to reduce the formation of fringes on the meat and the larding of the meat on knife or gauge plate.

The portion E of the member E serves to prevent the penetration of foreign material beneath the lower edge of the gauge plate C or the space beyond the flange D of the slice support D. As is clear from Figure-7 this eave portion E is also inclined outwardly over the edge of the refuse pan and bridges the gap between the refuse pan and the slice receiver. This bridging portion is continued as at E throughout the entire portion of the opposed edges of the two receivers.
